I need the sha of the second most recent git tag. When running
git show-ref --tags
i get
ab295f707bc42e8975fd4d87142ca436c0fac94f refs/tags/initial-commit-tag
1c816fc0895faeecd48b9b31e09ba825698f92a6 refs/tags/production-2018-03-06-001
which shows my two tags i currently have. How can i get it to output just ab295f707bc42e8975fd4d87142ca436c0fac94f?
I tried git rev-list --tags --max-count=1 --skip=1 but that apparently includes non tags as well, because when i run
git rev-list --tags --max-count=30 --skip=1
i get
d3d536c6745c823994b3fec8ce3b26caf2b4c6f5

so there are not only tags in this list. How can i filter for just tags in here/make the first command workable to only show the second recent one?
Note: am on Mac/Linux, so bash piping would work as well.
EDIT:
In the end the --no-walk option wordked for me, so
git rev-list --tags --max-count=1 --skip=1 --no-walk
The accepted answer below is much more powerful though.

In order to find the latest Git tag available on your repository, you have to use the “git describe” command with the “–tags” option. This way, you will be presented with the tag that is associated with the latest commit of your current checked out branch.
In order to checkout the latest Git tag, first update your repository by fetching the remote tags available. As you can see, you retrieve multiple tags from your remote repository. Then, retrieve the latest tag available by using the “git describe” command.
In order to create a Git tag for the last commit of your current checked out branch, use the “git tag” command with the tag name and specify “HEAD” as the commit to create the tag from. Similarly, if you want your tag to be annotated, you can still use the “-a” and “-m” options to annotate your tag.
To push multiple tags simultaneously pass the --tags option to git push command. When another user clones or pulls a repo they will receive the new tags.
You could refactor a bit your git command and pipe it to sed to extract the data you need :
git for-each-ref --sort=-taggerdate --format '%(objectname)' refs/tags | sed -n 2p
Explanation:
git for-each-ref : documentation link. Displays information about refs.
--sort=-taggerdate : reverse sort the output by tag date--format '%(objectname)' : we only output the hashrefs/tags: we only list the tags in refs/tagssed -n 2p: output only the 2nd lineNote that if you don't have a taggerdate on your tags, you can use other sort options, like creatordate (full list of available fields here).
